| 초록 |
In this paper, the compensation of ultrasonic scattering on interface crack depending on thickness variations of Al/Epoxy bonded dissimilar components was applied to improve measuring accuracy by using ultrasonic attenuation{{br}}coefficient. The optimum conditions of theoretical value and experimental measuring accuracy by the ultrasonic method in Al/Epoxy bonded dissimilar components have been investigated. From the experimental results, the measurement method of interfacial crack lengths by using ultrasonic attenuation coefficient was proposed and discussed. After the ultrasonic scattering compensation depending on thickness variations of bonded dissimilar components was carried out, the measuring accuracy of interfacial crack length was improved by 5%. |
